What are some examples of type hints in different programming languages?

Type hints are annotations that specify the expected data types of variables. For example, in Python, you can use:

def greet(name: str) -> str:
    return f'Hello, {name}!'

In TypeScript, you might see:

function add(a: number, b: number): number {
    return a + b;
}

Yes, can you show me examples in Java and C#?

Sure! In Java, you can use type hints like this:

public String greet(String name) {
    return "Hello, " + name + "!";
}

And in C#, it looks like this:

public string Greet(string name) {
    return "Hello, " + name + "!";
}

Let me know if you need examples from other languages!

What about Ruby and Go?

In Ruby, type hints are not enforced, but you can use comments for clarity:

def greet(name: String) -> String
    "Hello, "+name
end

In Go, you can specify types like this:

func greet(name string) string {
    return "Hello, " + name
}
